Every area is both living and non -residential should be fireproof. The concept of “fire safety” carries the resistance of the interior of housing or utility rooms to high temperatures for a certain time for which firefighters will be able to arrive at the fire site. The necessary recommendations regarding fire safety are written in the relevant law. It states that one of the most important elements of the premises, which one needs to pay attention to in the aspect of fire safety is the windows. And it does not matter what they are made of, of plastic or wood. Such requirements are understandable. With the spread of a fire, the influx of fresh air will contribute to fire. That is, oxygen that can come from a broken window, supports the burning of the flame. This means that the more reliable the fortresses will be double -glazed windows, the less the possibilities of the fire spread before the fire team arrives.
Windows made of plastic are much more reliable than wooden windows. Such a statement can be explained by different factors. Firstly, double-glazed windows have unique tightness, which means that the air flow from the outside will not be. Of course, if the windows in this case will be closed. Secondly, PVC is much worse than wooden structures. Often firefighters see an almost non -touched, but only with a sooty plastic profile. And finally, plastic windows can be equipped with fire safety systems. With their help, the speed of fire in the room will be minimal.
It is clear that PVC products are not the part of the premises that will be most vulnerable to fire safety. Probably the weakest place of any window is a double -glazed window. After all, it is made, in fact, from simple glasses that can burst due to the action of high temperatures on them. At the same time, the air entering the street can turn a small focus of fire into a huge fire wall. The double -glazed window can be considered fireproof if it can hold out when exposed to high temperatures at least 10 minutes. During this time, the firefighters team should have time to come to the call. In the conditions of large cities, where there can be car traffic jams, it is recommended to increase the double -glazed window protection time.
Modern manufacturers of plastic windows will improve technologies, and they know how to make PVC double -glazed windows most fireproof. To do this, use reinforced glass, glass hollow blocks or hardened glass. When conducting tests, it was found that if one side of the glass is heated to a temperature of 150 O Celsius, then the reverse side does not warm up more than 65 °. This is quite enough for the double -glazed window is not damaged by high temperatures. If you consider the fire safety of hardened glasses, then the fire can act on them for about fifteen minutes, after which such glasses will begin to deform, and will be able to hold the flame for some more time.
Reinforced silicate glass is equipped with a thin mesh. Thanks to it, when fire fire, the glass will not have a focus of expansion. In this case, the temperature will be scattered over the entire area of the double -glazed window evenly, which will allow the double -glazed window to move the temperature up to 850 degrees.
